Question

I have some files that need token replacement .. instead of the default single @, they use double @’s … So I need stuff like: @@replaceme@@ .. replaced.

Ant’s ReplaceTokens filter allows you to set it using BeginToken / EndToken .. Though I’m not sure how to configure it in my example:

copy{ 
  into something
  from somethingelse
  filter(ReplaceTokens, tokens: [])  
}

How can I change the above code to replace correctly work with double @@ tokens instead of single ones?

Answer 1

It’s easy to change the delimiters – just add named parameters beginToken and endToken to the filter method call. However, Ant’s ReplaceTokens only support single-character delimiters. A quick web search didn’t turn up an Ant FilterReader that supports arbitrary multi-character delimiters out of the box. An alternative is to code this yourself, either by implementing FilterReader or by using the free-form filter method.
